Shunt-Loaded Fractal-Meandered Microstrip
The fractal meandering approach to microstrip circuit miniaturization is limited by the need to maintain characteristic impedance. In this work we show that uniform and non-uniform shunt loading can be used yield a further level of miniaturization of Koch fractal meandered microstrips and is applied to the miniaturization of a 1 GHz bandstop filter. The miniaturized filter has an area 11% of the area of a filter using straight microstrips alone, and 57% of the area of a filter miniaturized by second order fractal meandering alone.
